Modified CMake target
Added ROOT analysis objects

Added the root analysis objects to the histomanager
Removed Analysis Messenger

Setting of the histograms is completed with the G4VAnalysisMessenger
class
Modified to use G4VAnalysiManager (histManager)

Modified the code to use the G4VAnalysisManager contained in
histManager while removing uncessary functions.  I think I need to
voxelize by geometry in replicas in the mother volume, and then create
an array of Sensitive detectors which I can pass in and then analyaze.
